BUNDLE-DELIVERING: MECHANISM FOR THRESHINGrMACHINES.

Specification of Letters Patent.

Patented Mar. 28, 11916.

Application filed June 12, 1914, Serial No, 844,683.

To all whom it mayeoncern Be it known that 1, AND EW J. PETERSON, acitizen of the United States, residing at Isanti, in the county ofIsanti'and State of Minnesota, have invented certain new and usefulImprovements in Bundle-Delivering Mechanism for Threshing-ll/laehines,of which the following is a specification.

My invention relates to bundle-delivery mechanism for threshing machinesand has nected in such relation to the threshing cylinder and feedermechanism of a threshing machine, that bundles conveyed by said carrierswill be delivered to said feeder mecha nism and threshing cylinder inexactly the same relative position regardless of the angle at which saidcarriers may be turned" in respect to the separator, and whether turnedto the front or rear. In accompllshing this object I provide meanswhereby the bundles are conveyed by the carrier mechanism and deliveredto the feeder mechanisn i and threshing cylinderdirectly downward; thatis, at the time of delivery the bundles are turned in a substantiallyvertical position so that the direction at which the carrier is turned,whether to the provide a pair of such carriers so related to thethreshing cylinder that the bundles conveyed by each carrier go to aportidn only of the threshing cylinder, so as to be operated uponindependently of bundles conveyed bv the other carrier. Thetwo carrierscoeperate in producing a thoroughly efficient feed because onecannotintroduce its bundles to the part of the cylinder operating uponbundles from the other carrier, and because this form of distributioninsures the uniform operation of the entire threshing cylinder whenbundles are conveyed from both carriers. The range of movement ofthe twocarrier wings is so great that both carriers may always be employed infeeding the engine cylinder, even when there is only one stack to bethreshed. Both carriers may be swung so as to feed from'the same side ofthe machine. Each of the carriershas range of movement for variousfeeding positions through more than one hundred and eighty degrees. I

A further object of my invention is to provide novel and efficient meansfor controlling the carriers, to raise and lower the same, and effectivemeans for driving the conveyers of the carriers throughout the range ofswinging movement of the carrier wlngs.

The full objects and advantages of my invention will appear inconnection with the detailed description thereof and are particularlypointed out in the claims.

In the drawings,illustrating the application of my invention in oneform, Figure 1 is a side elevation of a portion of a threshing machineshowing my bundle-conveying members applied thereto, the carriers beingin working position when turned in opposite directions. Fig. 2 is a viewof some of the parts shown in Fig. 1 on a somewhat larger scale showingsome of the driving mechanism. Fig. 3 is a sectional elevation on anenlarged scale showing the relation of the carriers to the feedingmechanism and the means for controlling the elevation of the carriers.Fig. i is a plan view of the mechanism showing a portion only of thecarriers and with some parts in section. Figs. 5 to 8 are diagrammaticrepresentations of the separator showing differ ent wo king positions ofthe carriers.

As illustrated, I provide a casing 10 which is adapted to be securedupon the front of the separator above the threshing cvlinder, indicatedin dotted lines at 11. Upon the top of casing 10 are secured two pairsof rings 12, 13 having flanged lips 14. 15, as best shown in Fig. 3.Each of a pair of hoods 16, 17, is provided with a cys lindrical basering 18 having a peripheral rib 19 journaled between ball bearings '20positioned on either side of said rib and held by the lips 1-1, 15 ofrings 12. 13. It will thus be apparent that the hoods 16 and 17, whichrise vertically above the rings 18 and open throughout the circular areainside of said rings into the casing 10 are free to rotate in ahorizontal plane upon said ball bearings. The hoods 16, 17. and theparts connected therewith, are identical in all particulars and,therefore, the respective parts for each hood will be referred to by thesame reference characters.

forwardly-extending portions 21 of the hoods 16, 17, so that they rotatefr'eely therewith; but said troughs are journaled to oscillate invertical planes on shafts 28. The shafts 28 have thereon sprocket wheels29, which operate the carrier chains 25, power being communicatedthereto in any position of said carriers, as will be later po nted out.

For controlling the elevation of the carriers 23 and 24 I provide thefollowing mechanism: A fulcrum support is formed of bars 30, 31pivotally secured at their lower ends to shaft 28 and connected adjacenttheir free upper ends by a crossbar 32. Upon the crossbar is pivotallysupported an arm 33 terminating in a yoke 34, in which is journaled acompound pulley 35. A cable 36 has one end secured to ablock 37pivotally anchored at 38 to a casting 39 bolted to cover 21. The cableruns from the point of fastening about one member of pulley 35, about apulley 40 in block 37, about the other of pulleys 35 to a drum 41 looseon a shaft 42, which is rotatably iournaled in bearings, 43, 44 securedto casting 39. The drum 41 is fast with a sleeve extension carrying aworm wheel 45 meshing with a worm 46 journaled in bracket extensions 47-of bearing member 43. It will thus be apparent that the supportconsisting of bars 30, 31, and crossbar 32, is held in position by meansof the block-and-tackle arrangement above described from drum 41, sothat by operating the worm 46 by means of hand crank 48, the support maybe readily raised or lowered. as desired. Extensions 49 and 50 of bars30 and 31 have journaled therein pulleys 51 and 52. The carriers 23 and24 are each directly supported by means of cables 53, 54, which arefastened at 55 and 56 to the sides of the carrier and run over pulleys49 and 50 to drums 57 and 58 fast on shaft 42. The shaft 42 also hasfast thereon a worm wheel 59 meshing with a worm-60 on a vertical shaftjournaled in a bracket 61 extending from bearing casting 44, and havinga crank 62 thereon. It will top of cover 21. A Mounted upona verticalshaft 68 in casing 69 is a double bevel gear 70, the lower bevel face ofwhich meshes with a bevel'gear 71 on shaft 68, while the upper facemeshes with a bevel gear 72 on a shaft 73 journaled in both casings 69and,

therefore, held rigidly fixed with said casings. It is to be observedthat the casing 69, as best shown in Fig. 3, is sectional, so that theportions thereof may move relatively, the lower portion being fixed inrelation to the top 21 of hoods 16 and 17, while the upper portion isfixed in relation to the shaft 73. The carriers, therefore, are free torevolve about the axis formed by vertical shaft 68 while retainingdriving connection with shaft 73. -The shaft 73 has thereon midwaybetween hoods 16 and 17 a sprocket wheel 74 operated by a sprocket chain75, which, in turn. is driven by a sprocket wheel 76 on shaft 77, uponwhich is mounted one of a pair of feeder rollers 78, 79 within casing10. The shaft 77 has thereon, outside of casing 10, a sprocket wheel 80driven by a sprocket chain 81 from a sprocket wheel 82 extending fromsprocket wheel 80 on a shaft 83 of the thresher cylinder. Band cuttermechanism 84, and feed governor mechanism 85 within hoods 16 and 17, arealso dri en from the above described means.

The feed rollers 78 and 79 extend directly across beneath the verticallydownward discharge openings of hoods 16 and 17 and above the threshingcylinder indicated in dotted lines at 11.. The discharge of rollers 78and 7 9, if such rollers are used, and the portion of the threshingcylinder between the axis of the cylinder and the threshing concave arepositioned beneath the center of the vertical discharge openings of thehoods 16 and 17. It will be apparent, therefore, that all bundles comingfrom a carrier 23 or 24 will drop downwardly off of the end of conveyer25. and will pass between feed rollers 78 and 79 to the threshingcylinder, or directly to the threshing cylinder, in

the same relative position with respect to the threshing cylinderwhatever may be the angle of the carriers 23 and 24 with respect to theaxis of the threshing cylinder. It will therefore be apparent that eachcarrier delivers its bundles to a particular. portion of the threshingcylinder and that the delivery of bundles by one carrier cannot over:

lap upon that of the other carrier, so that the feed from the twocarriers results in uniformity of grain delivery across the entirelength of the threshing cylinder and the carriers cannot pile up thebundles at one part only of the threshing cylinder so as to causeslugging and inequality of work.
